ABSTRACT:
An apparatus for the treatment of the lacrimal duct in which both ends of a thinner and softer tube or rod 0.5-0.7 mm OD and 20-40 mm in length are connected with thicker and harder tubes (0.9-1.2 mm OD and 15-50 mm in length), resulting in a total length of 50-120 mm. Both ends (2 mm) are sealed by silicone to make the closed end and then formed sharp pointed in conical shape.
